In the legends are described the main parameters that have been used to fit the data with (Eq. (4)). The slope response for f > 10 Hz is mainly affected by n0 and the quality factor (Q). A better fitting for all proposed geometries in the slope for f > 800 Hz is found for low Q (overdamped systems) and original natural modes f01 values. The cut-off frequencies are 1500 Hz (Geom. A), 940 Hz (Geom. B), and 620 Hz (Geom. C)
